Argentine electroacoustic composer Beatriz Ferreyra worked at INA-GRM in Paris in the 60s, and after being shown how to cut tape and mix by Pierre Schaeffer, embarked on a sonic journey that was completely her own, and which continues to this day - the longest piece here, Senderos de luz y sombras (Paths of shadows and light) was freshly minted in 2016/17 and was receiving its UK premiere at Electric Spring.
Alongside Senderos, Ferreyra's evocation of the universe before and just after the big bang, two older pieces were featured. Echos was originally put together in the late 70s, from tapes of the composer's niece who had passed away in a car accident. Four acapella tapes of her singing were mixed together into a wonderfully affecting whole, complete with a poignant moment of laughter at the end. The other work is Rio de los pájaros azules (River of the blue birds) from 1998, in which a dream of a lush, Latin American landscape is channeled into a beautifully alien-sounding fantasia. All very listenable and fascinating stuff - recommended.

N.B. cover art used is not from the actual Feb 2017 performance, but I believe it is a fairly recent picture - thought it would be a good fit when I found it.
